Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of anticancer agents. It serves as a building block for tyrosine kinase and cyclin-dependent kinase (CDK) inhibitors due to its structural compatibility with ATP-binding sites in enzymes. Also employed in the preparation of bioactive indole derivatives with potential antitumor and anti-inflammatory properties. Its bromo functional group allows for further modification via cross-coupling reactions, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies.
